Singlet oxygen emission and peroxide generation at the surface of molybdenum–vanadium oxides evidenced that the catalytic activity of a MoO3:V2O5 mixed oxide at 70–175 °C was governed by the formation of peroxo groups in the interaction of molecular oxygen with adjacent Viv surface centers; the thermolysis of these groups yielded singlet oxygen capable of oxidizing selectively alcohols to aldehydes.

One-pot two-step synthesis of γ-keto sulfones in deep eutectic solvent 在深共晶溶剂中一步两步合成γ-酮砜
IF 1.8 4区 化学 Q3 CHEMISTRY, MULTIDISCIPLINARY Pub Date : 2024-09-01 DOI: 10.1016/j.mencom.2024.09.027
Acidic deep eutectic solvent was prepared from choline chloride and trifluoromethanesulfonic acid at room temperature. Reaction between aromatic aldehydes and arylacetylenes in this solvent gave chalcones whose in situ reaction with sodium arenesulfinates in water successfully provided γ-keto sulfones in good yields. This deep eutectic solvent could be easily recovered and reused for several runs.

Two novel conjugated polymers comprised of 2,3-R2-di- thieno[3,2-f:2,3-h]quinoxaline, where R is 3-(octyloxy)- phenyl (P1) or 2-(2-ethylhexyl)thiophen-4-yl (P2), and 2,1,3-benzothiadiazole have been synthesized using the Stille cross-coupling reaction. The synthesized polymers were investigated as hole transport layer (HTL) materials in perovskite solar cells. Polymer P2 as an HTL material provided improved short-circuit current and open-circuit voltage and, correspondingly, enhanced power conversion efficiency of perovskite solar cells compared to that of polymer P1.

Key features of perovskite solar cells operando stabilization with ionic liquid choline cinnamate 用离子液体胆碱肉桂酸盐稳定过氧化物太阳能电池的主要特征
IF 1.8 4区 化学 Q3 CHEMISTRY, MULTIDISCIPLINARY Pub Date : 2024-09-01 DOI: 10.1016/j.mencom.2024.09.011
The ionic liquid choline cinnamate was applied for the first time as a defect passivator in light-absorbing layers of perovskite solar cells (PSCs). It was found that bulk passivation with an addition of 0.5% ionic liquid notably enhances the photothermal stability of PSCs, while surface passivation leads to the opposite effect with the loss of device stability, due to the complex origin of the influence of choline cinnamate on the defect structure and microstructure of hybrid halide perovskites.
离子液体肉桂酸胆碱首次被用作过氧化物太阳能电池(PSCs)吸光层的缺陷钝化剂。研究发现,添加 0.5% 离子液体的体钝化可显著提高 PSC 的光热稳定性,而表面钝化则会导致相反的效果,使器件失去稳定性,这是因为肉桂酸胆碱对混合卤化物过氧化物的缺陷结构和微观结构的影响来源复杂。

Sol–gel prepared ZnO: UV irradiation effect on structure and surface properties 溶胶凝胶制备的氧化锌:紫外线辐照对结构和表面特性的影响
IF 1.8 4区 化学 Q3 CHEMISTRY, MULTIDISCIPLINARY Pub Date : 2024-09-01 DOI: 10.1016/j.mencom.2024.09.006
The effect of UV irradiation on sol–gel prepared ZnO films subjected to mild thermal annealing was investigated, with special attention to their structural and surface properties. Sol–gel processes, including a high-temperature annealing stage, have been adapted to the requirements of flexible electronics for in situ synthesis of semiconductor ZnO films on polymer substrates at lower temperatures due to UV irradiation. Application of UV radiation with emission peaks at 185 and 254 nm to films annealed at 180 °C made it possible to obtain ZnO films with Zn/O ratios of ca. 1, which cannot be achieved by heat treatment alone.

Does the 57Fe Mössbauer isomer shift depend on the oxidation state of iron? 57Fe 莫斯鲍尔异构体位移是否取决于铁的氧化态?
IF 1.8 4区 化学 Q3 CHEMISTRY, MULTIDISCIPLINARY Pub Date : 2024-09-01 DOI: 10.1016/j.mencom.2024.09.002
The 57Fe Mössbauer isomer shift is not directly related to the oxidation state of iron, and therefore the evaluation of the oxidation state of iron from the isomer shift is problematic. The oxidation state affects the isomer shift only to the extent that it affects the Fe–X bond lengths. The isomer shift can be estimated based on the average Fe–X interatomic distance.
